BORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 258,716, dated May 30,1882.

Application filed March 16, 1882.

To all whom it may concern:

Be it known that I, VINCENT 00X, of New 2 is a vertical longitudinalsection of the same.-

This invention consists in a machine or tool of simple construction,whereby every facility is afforded for boring holes in wagon or buggyfellies and other articles both in straightlincs and in various angulardirections without shifting the article being bored, substantially ashereinafter described.

A in the drawings indicates the frame or stand of the machine on whichthe felly B or other article to be bored is placed, and upon which it issecured by a clamping-screw, O. Said frame A is here shown as formed ofa table or base, 0, upon which the folly rests, and an open guard, I),projecting upward from the front of said base, and against which theinner side or one edge of the telly bears. Attached to and projectingcentrally and horizontally outward from the frontof this frame is anarm,

. D, having an eye, 1, opening up through its outer end andfitted with aside set-screw, c, for holding in place, as adjusted up or down oraround within said eye, a circular post, E. This post is alsoconstructed with an eye, at, at its upper end, whereby it is made toform the bearingpost for the shaft or rotating holder G, which carriesat its inner end the bit or auger G, and which shaft corresponds withthe shank of the bit or anger. This shaft G is fitted to work loosely orfreely through the eye (I of the post, and is provided on its outer endwith a crank or handle, 0, for operating the bit or anger.

With the machine or tool thus constructed every facility is afforded forboring either a straight hole through the fclly without gaging (Nomodel.)

or marking that is, a hole parallel with the arm D or a hole at anydesired angle theretoand inclining up or down or to the right or left,the adjustability of the post E, longitudinally and axially, and freefit of the shaft Gr through its eye, providing for such varied action ofthe boring-fool. For ordinary variations in the angular direction oftheholes to be bored, and for straight holes, it will notbe ncc cssary evento disturb the bearing of the shaft G or move the post E, as the hole inthe eye at of the post is constructed with arolling bearing-surface forthe shaft G-thatis, a bearingsurface in which the shaft G is free toroll in vaiious directions, as shown in Fig. 2.

Upon the base a of the frame A is a centering projectiomf, in line withthe arm D, whereby the adjustment of the telly on the frame and properdirection of the-bit at starting is facilitated.

The machine, which is simple, cheap, easily adjusted, and not liable toget out of repair, may be used not only for felly-boring or boring holesin curved pieces of timber, but also for boring holes in straight piecesof scantling or timber f r making gates or other carpenter work.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1. The combination, with the frame A and theclamping-screw O, of the bit orauger holding and operating shaft G, andthe supportingpost E, having a rolling bearing-surface, substantially asherein shown and dcscribed,whereby the direction of the bit or anger canbe varied, as set forth.

2. The combination, with the frame A, provided with a clamping-screw, O,and forwardly-projecting arm D, of the post E, adjustable bothlongitudinally and axially within and through said arm, and thebit oranger holding and operating shaft G, supported in an eye,d, ofsaid post,constructed to form a bearing having a rolling surface, essentially asshown and described.

- VINCENT 00X.
